Satellite infrared image of the US-Canada border, showing Montana, southwestern Saskatchewan and southeastern Alberta, Canada. This area is cattle grazing territory for the Canadian provinces, but is wheat growing land for the US side of the border (where cattle is grazed further south). The Milk River cuts across the image diagonally, and a small outlier of the Rockies stands out in red (vegetation) in this northernmost part of the Great Plains.

Eastern Oklahoma is much more moist than the western Panhandle part of the state.

 

Signs along the freeway in Oklahoma mark the former American Indian reservations in the state.


Tulsa, Oklahoma sits near the banks of the Arkansas River.

Red dirt and blue skies in western Oklahoma.

 

This is the heart of Tornado Alley

Crossing the Great Plains - somewhere in Oklahoma. Tucumcari is in New Mexico.


Texas State Line near the Oklahoma Panhandle


Somewhere in Central Texas.



The Alamo near what is now downtown San Antonio, Texas. Below and to the east of San Antonio one drops off the Great Plains and into the Lowland South (where Houston is located).

 

A portion of San Antonio's famous downtown River Walk.


F.M. = Farm to Market roads. You also see R.M., Ranch to Market, roads in rural Texas. We are somewhere between San Antonio and Houston here, in a much more humid area.

 

The Llano Estacado - with a wind generator in the background. This State of New Mexico historic marker is located close to the border between Texas and Oklahoma.


The Llano Estacado (Staked Plains in Spanish) is possibly the driest part of this region.
The red dots in this infrared image are fed by the underground Ogallala Aquifer. The left third of this image is higher land -- the beginning of the Rocky Mountains and the Mountain West region.
